Effect of Feed Granule Machining on Feed Nutritional Quality

When using the feed granulator, the feed raw materials will be processed. Some consumers have doubts about whether the nutrient components of the feed will be damaged in the feed processing process, and will it lead to the loss of feed nutrition? Henan Feed Machinery takes you to understand these problems:
In the granulating process of feed granulator, the main functions are friction, pressure and high temperature to allow feed processing, and the temperature of fresh particles is above 80 ℃. These physical effects have two effects on the nutritional quality of feed.
On the one hand, strong, high temperature and high pressure can mature the feed protein, gelatinize the starch to a certain extent, produce a certain flavor, improve the digestibility of nutrients, and increase the palatability of animals; High temperature can kill pathogenic microorganisms and parasitic oocysts in feed to a certain extent, reducing their harm to livestock; High temperature can also destroy some anti nutritional factors and anti feeding factors in feed to a certain extent. Anti nutritional factors such as trypsin inhibitor, phytohemagglutinin, glucoside, etc. These substances will hinder the absorption of feed nutrients by animals. There are "anti feeding factors" - non starch polysaccharides in feed, such as β- Glucan, polysaccharide, cellulose, pectin mannose, etc. It is difficult to be decomposed by endogenous joke enzymes of monogastric animals, and it is delicious.
